Q: Why do we need both v1.03 and v1.04ff, which should I use?A: If you are not going to use anything older than 257.21 – forget about v1.03 and usev1.04ff. The mod v1.03 is intended for old 19x series and 9.10.0222 (+older) PhysX SS.

If you update any component from the [old] 19x.xx and/or 9.10.0222 (+older) to [newer] 256 series and/or 9.10.0223 (+newer) – you should apply the mod v1.04ff afterwards. The mod v1.04ffwill not help with 19x series GeForce driver.

Did you run FluidMark and GPU-Z to check GPU PhysX? For FluidMark remember to remove the PhysXDevice.DLL from the Programs folder else it wont work. You wont see anything in the Nvidia Contol Panel as to whether or not PhysX is working.

Hi, yer I’m seeing the same thing. In the nvidia control panel there is no menu option for Physx, it just doesn’t appear. I think physx is still working as I used a benchmark and GPU appeared next to the CPU. Still, it is more reassuring to see the menu option in the Nvidia panel

In a Hybrid setup you cannot get access to the PhysX options in the Nvidia Control panel. This is normal.
